SetMovable() function and userdata class

[SmashingQuasar]

Hey everybody,

So my friend and I are currently working on an addon to vastly improve ESO's character sheet.

We found out that the character sheet object is: ZO_StatsPanel
It has for parent GuiRoot (well basically, the game window), problem is, I tried to use the method SetMovable() on ZO_StatsPanel (ZO_StatsPanel.SetMovable(true)) but it created an error stating SetMovable() expects the parameter to be of userdata type, not boolean. When I read the extremely sparse API documentation, I found the SetMovable() function, which expects the parameter to be boolean.

So I'd like to know what is the userdata class? (I assume it's an object class)
I'd also like to understand how to use this method on this panel.

Thanks a lot

You need to call it like this:

ZO_StatsPanel:SetMovable(true)

which is the same as this:

ZO_StatsPanel.SetMovable(ZO_StatsPanel, true)

Oh, I didn't know methods were called with : in lua :> Didn't even consider it in fact which is a shame xD

Thanks a lot for your help, any idea why the background texture isn't moving with the window now that my code works?

They don't "have" to be called with :
Using the : just tells it to pass the calling object as the first parameter, so if you use : and type this:

ZO_StatsPanel:SetMovable(true)
-- the : really means it is going to pass 
-- these parameters: (ZO_StatsPanel, true)

As sirinsidiator said, you could also call

ZO_StatsPanel.SetMovable(ZO_StatsPanel, true)

Notice here the : is not used, but we manually type in the parameter ZO_StatsPanel as the first parameter.

As for your background, it is because that background (ZO_SharedStatsBackground) is not part of the window ZO_StatsPanel, its just a shared background that gets hidden/shown when its needed.

Thanks for your help, I managed to do a lot of things I wanted to, and it's starting to take shape, I've one more question while this thread is alive.

Is there a way to know when the player opens the character sheet (ZO_StatsPanel) ? My problem is: All the children do not exist when the character sheet isn't open, and thus preveting me from changing their position/hiding them.

Here you go:

local function OnStateChange(oldState, newState)
    if newState == SCENE_SHOWN then
        -- its now visible, do whatever
    end
end
STATS_SCENE:RegisterCallback("StateChange", OnStateChange)

Possible results for oldState & newState are:

SCENE_HIDING  -- (the scene is in the process of hiding, but not yet finished)
SCENE_HIDDEN -- (the scene has finished hiding)
SCENE_SHOWING -- (the scene is in the process of being shown, but not yet finished)
SCENE_SHOWN -- (the scene has finished showing)

Thanks for your help, I totally reworked my code so the add-on does not process the modifications when loaded but only when the character sheet is opened. I have other questions but I think I'll open another thread since it's unrelated to my first question.

Thanks again guys, really saved my life
